Strong Minds: A Digital Intervention Targeting Body Image and Psychological Well-being Among Adolescent Male Fitness Club Members
Sponsor: Norwegian School of Sport Sciences
Summary
The purpose of this study is to evaluate whether a digital intervention can improve body image and psychological well-being among adolescent boys who attend fitness clubs. Fitness club environments and social media often promote appearance ideals related to muscularity and leanness, which may contribute to body appearance pressure, body dissatisfaction, and psychological distress among boys. In this cluster-randomized controlled trial, approximately 260 boys aged 15 to 18 years will be recruited from fitness clubs in Oslo, Norway. Participants from fitness clubs assigned to the intervention group will receive access to a 12-week website-based program consisting of four interactive modules focusing on body image, psychological well-being, critical social media literacy, and attitudes toward food and sports supplements. Participants in the control group will continue their usual activities. The study will examine whether the intervention reduces internalization of appearance ideals and body appearance pressure and improves body appreciation, health-related quality of life, psychological well-being, social media-related behaviors, and attitudes toward food and sports supplements. Outcomes will be assessed at baseline, immediately after the intervention, and at a 6-month follow-up.
